i thought the cherrybomb extreme was to raspy and popping , this flowmaster sounds deep and mean, sounds more of a v8 now and i kinda hear more of a lope with my 1.7 harland sharps. throttle resonce seems better too.

 

I don't know how it could sound much different, the FM10 is a clone of the CB Extreme, although they are made of different materials.

Have a buddy with a Z71 who went the other way, from a FM10 to a CB Extreme and nobody could tell he changed anything.

Is the ONLY difference the muffler???

Although I have heard two different 4.7 Rams with the CB Extreme, one a side exit right behind the cab and the other a dual out the rear and the side exit one does pop a LOT where the dual rear truck never pops and is MUCH deeper, so I guess differences in piping, location, etc. can make a big difference...

 

From what I read the chamber is diffrent , one is a "v" and other one is a ""L"

It's a totally diffrent sound to me now. I dunno

 

Between me and my friends we have done DOZENS of exhaust systems on trucks, and the thickness of the pipe, location of the muffler within the tubing, and length/size of tubing makes almost as big of a difference as a muffler alone.
